They are in Phase II and started it in January 2012. 3 month results should be available in the next few months.
This is where Intercytex fell down. It's crunch time for Histogen. If they can improve on their Phase I results which were 20% increase in terminal hairs at 3 months (compared to Replicel's 3% at 6 months!) then I imagine they will have a marketable product.
If they do an Intercytex then... well, Aderans is our last hope. And that is a particularly depressing thought.
